The Q'Straint DropLok Universal Securement Kit (Large) is the case-side retrofit component that brings your existing large EMT bags, hard-shell ALS cases, and full-size LokBox cases into the DropLok crash-certified securement system. Attach the Stabilizer Plate and Securement Plate to your large portable case and it becomes fully compatible with any DropLok Easy Mount with Safe Release (Q10-005) installed in the vehicle. The complete DropLok system is SAE J3043 certified — the same crash standard Q'Straint applies to cot securement systems — meaning your large ALS bag stays locked to the wall in a frontal or side-impact event just as securely as your patient's cot. Keep your existing cases. Make them crash-compliant.

-
Install the Easy Mount with Safe Release (Q10-005) — 4 bolts, mounted vertically on the ambulance wall or horizontally on a countertop or module shelf.
-
Attach this Retrofit Kit (Q10-004) — secure the Stabilizer Plate and Securement Plate with Straps to your large EMT bag or full-size LokBox case.
-
Load and Lock — engage the retrofitted large case into the wall-mounted Safe Release. It secures automatically. No extra steps.
-
Instant Deployment — trigger the top button or bottom release; the large case is in your crew's hands in one motion.

Frequently Asked Questions
What's the difference between the Small (Q10-003) and Large (Q10-004) Retrofit Kits?
The Small Retrofit Kit (Q10-003) is sized for EMT bags with dimensions between 7.5"–14" (L) × 11"–18" (W) — typical BLS jump bags, portable AEDs, and small drug boxes. The Large Retrofit Kit (Q10-004) is designed for larger cases that exceed those dimensions, such as full-size ALS tackle boxes, large hard-shell ventilator cases, or Q'Straint LokBox cases. If you're unsure which kit fits your case, call us at 800.884.6456 with your case's exterior dimensions and we'll confirm the right fit before you order.
Do I need to buy anything else to use this kit?
Yes — the Q10-004 is the case-side component and must be paired with the Q10-005 Easy Mount with Safe Release installed in the vehicle. Both are required for a functional DropLok installation. If you're looking for a complete out-of-the-box bundle that includes the wall mount, this retrofit kit, and a Q'Straint LokBox case, see the Q10-008 Complete System.
Will the straps work on both soft bags and hard-shell cases?
Yes — the Securement Plate with Straps and Buckles is designed to work with both soft bags and hard-shell cases. For soft bags, the strap system cinches around the bag body to hold the Stabilizer Plate firmly in position. For hard cases, the hardware attaches directly to the case structure. The DropLok design philosophy is to keep existing agency equipment in service — whatever your current large case is, the kit is built to retrofit it.
Can I use multiple Large Retrofit Kits in the same ambulance?
Yes — each Retrofit Kit configures one bag or case, and each requires its own Easy Mount with Safe Release (Q10-005) at a separate vehicle mounting position. Agencies deploying multiple large cases per unit can have multiple independent DropLok stations. Contact us for multi-unit and fleet pricing at 800.884.6456.
